China has been known as "the country of jade" since ancient times. The ancients regarded jade as a treasure and regarded it as a precious ornament. Ancient medical books say that "jade is the beauty of stone, sweet, flat and non-toxic", and it is considered that jade is the most abundant substance in human body. It is believed that jade absorption can "promote fluid production to quench thirst and remove stomach heat" with the help of saliva and its synergistic effect.

Soothes the troubled place, nourishes the heart and lungs, moistens the throat and promotes hair growth. "Therefore, jade is not only used as jewelry, ornaments and decorations, but also used to keep fit. Since ancient times, emperors and concubines of various dynasties have not used jade to keep in good health, while Song Huizong loves jade and Yang Guifei has jade to relieve the heat.

The health-preserving mechanism of jade has been confirmed by modern science. According to chemical analysis, jade contains many trace elements beneficial to human body, such as zinc, magnesium, iron, copper, selenium, chromium, manganese and cobalt. Wearing jade can make trace elements absorbed by human skin, activate cell tissue and improve human immune function. Therefore, some Chinese medicine practitioners say that "some diseases can be cured not by taking medicine, but by wearing jade often", which is the truth. If you wear a jade bracelet for long-term benign massage, you can not only passively remove the disease of blurred vision, but also store your vitality and nourish your spirit.
